f'(x) = 4*sqrt(f(x))

f'(x) = 4*sqrt(f(x))

[derivative with respect to x of f(x) = 4 * squareroot of f(x)]

Does anyone know how to solve equations like this? The goal is to solve for f(x). I run into equations like this so often and always get stuck.

Math Focus: Mainly analysis and algebra
Separation of variables.

$$y'=4\sqrt{y} \implies \int y^{-\frac12} \, \mathrm dy = 4\int \mathrm dx$$
